To all whom it may concern: the body Y); it is, however, equally feasible Be it known that 1, JOHN ALBERT FINCKE, to produce the veneer by applying the a citizen of the United States, residing at 1 materials recited on the top of the body or 30 Beekman Place, in the borough of Mancore 7o when formed iii the mold. lt must, hattan, city of New York, and county and of course, be understood that in either way State of New York, have invented new and of manufacture the veneer a must be joined useful niprovements in Waterproof Cement l to the body or core before the grout or Blocks and in the Manner of Applying the cement mixture has set. The outer surface Same, particularly in constructing what is sired manner.

The bituminous backing c is applied after tures;7 of which the following is a full, clear, y

and exact specification, reference being had the veneer a and core l) of the block have to the accompanying drawings, wherein# l set. This is done by immeising the block Figure l is a sectional view, on a vertical in a vessel, containing molten bitumen, to a line, and Fig. 2 a similar view on a horidepth `corresponding to the thickness of tie zontal line, showing the construction of such f body or core b, holding the veiicered face blocks and the joint-s betweenthem; Fig. 3 l thereof on top. Before such immersion, the is an isometric view of a clamp .employed for l block should be heated to about M to 175o fastening together the vadJoining blocks in I F. The immersing o-f the blocks is prefersuch structure; Fig. ta similar view of my ably done in an open and adequately deep improved cement blocks, showing the vessel containing a larger quantity of the grooves and recesses for the insertion of the i molten bitumen and provided with suitable clamp to fasten together two adjoining arrangement, to prevent iinmersing of the of the vencer a may be finished in any de- "f blocks; Fig. 5 is an isometric view of such a l blocks too deeply. Tn such deeper vessel the t block and of the anchor for securing it to bitumen can be kept in a constantly molten the fraine-woik of the structure; Fig. 6 is a state, by heating the bottom of the vessel similar view showing such an anchor apart and the blocks may be handled more easily from the block in reversed position to that and without danger of soiling or defacing shown in Fig. 5; and Fig. 7 is an isometric their veneered surfaces.

The core Z) is made of the bitumen, may be applied thereon. This ordinary hydraulic cement and sand, formed addition, however, need be resorted to only lin plastic state and reinforced by metal lath in exceptional cases. For ordinary purof any suitable character. Tn forming the poses, it will be found amply sufficient to core, the metal lath is embedded in the "oduce the backing c by merely immersing plastic mass in the usual manner while in the the blocks when set, dried and heated in the mold, to form a stiffening or reinforcing molten bitumen as above explained.

The veneer a is As will be seen with reference to Figs. composed of a water-proof mixture of P'ort- 1, 2, 4C and 5, the core b of each block is land cement and sand with the addition of a provided with corresponding grooves and suitable proportion of silicate of soda and any l tongues g and g, so that when the blocks coloring matter as may be desired. By using are joined together, the tongue of one enters with the cement, a small proportion of finely the corresponding groove of the other. The ground, burnt clay, a water-proof veneer backing o of the bituminous material exreseinbling closely terra cotta, both in color tends to the sides of the core l), as shown in and in appearance, is produced. This veneer Figs. 1 and 2, and therefore, in forming the a, is preferably united with the body or grooves g and the tongues g', this circumcore b of the block in the process of its stance must be taken in consideration an manufacture. This may be done by spreadthe tongues g be made correspondingly ing the material for the veneer on the botsmaller, and the grooves g correspondingly tom of the mold and then applying thereon larger, to permit snug joining of the blocks the cement and sand grout, used for casting together.

Y hook 1s The horizontally adjoining blocks are fastened together by clamps j, suchas shown in ig. 3, and for this purpose, recesses j, formed in the tongues g', and grooves jg are provided,'the grooves ji extending from tl e recesses y" to the edge of each block, to permit embedding therein of thel clampsY y', as shown in sectional vieW in F ig. l.

For securing theblocks to the frame-Work of the structures such Fig. G are employed. 'Th hook-shaped point yt, and a formed to emb of the block, and suitable recess is provided in the groove g of the block and in the adjoining flange, to receive the anchor.
